The Shield & Seal Pipeline
Four steps between your art and the machines that want to swallow it.
SHIELD
Before your art leaves your device, we harden it. Adversarial pixel patterns — invisible to the human eye — are woven into every image. These patterns are specifically designed to poison AI training pipelines. Your art becomes toxic to scrapers while remaining beautiful to humans.
HASH
We compute a unique fingerprint of your hardened asset using SHA-256 cryptographic hashing combined with perceptual fingerprinting. This means even if someone screenshots or slightly modifies your work, the perceptual hash can still trace it back to you.
SEAL
Using your device’s Secure Enclave (FaceID or TouchID), you create a biometric signature that binds your living identity to the asset. This signature is wrapped in a C2PA manifest — the emerging industry standard for content provenance. Your face. Your art. Cryptographically bound.
REGISTER
The final step publishes a zero-knowledge proof of your hash and public key to the Humark public registry. Anyone can verify your work’s authenticity. No one can forge your identity. The record is permanent and tamper-evident.
